is there any way to get unid snapdragon other than killing the high level monsters?

Random events.

Requirements : Must have access to fairy rings

 

Items:

 

-I suggest a ranging gear, maging is a waste of runes and don't even think about melee.

 

-An axe

 

 

 

Go to B K Q with the fairy rings and chop a tree. find a safespot and range the tree spirit. Repeat. They drop all kind of axes, nats, herb seeds(including toadflax and snapdragon) and unidentified herbs(including toadflax and snapdragons) some other drops I don't remember too. Might not be super fast, but eventually you'll end up with at least one snapdragon.

trading in tickets at brimhave agility course can give you snapdragons, but I'm not sure wheter they are unid or not.
